Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel-mounted electrical connector.

Conventionally, in electrical connectors that are mounted on a panel, the panel mounting part and the cable connection terminal part are integrated. With the electrical connector already attached, the core wire of the cable had to be connected by soldering or crimping to the cable connection terminal section. If you connect the terminals to the terminals at the site where the equipment's exterior assembly is being assembled, it is easy to make wiring mistakes, and it is difficult to use a wiring jig for batch wiring. There was a problem. In addition, when attaching the electrical connector to the panel after the cable has been connected, it must be attached from inside the device, which may cause problems such as limiting the thickness of the panel and making the attachment work difficult. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a panel-mounted electrical connector that eliminates the drawbacks of the conventional panel-mounted electrical connectors as described above and can streamline equipment exterior assembly and wiring work.

According to the present invention, a panel mounting type electrical connector is divided into a frame body fixed to a panel and a terminal part that can be attached to the frame body after being fixed to the panel. The terminal part can be attached to the frame body simply by inserting the terminal part, and moreover, the terminal part will not fall off from the frame body even if a mating connector is erroneously fitted.

According to this configuration of a panel-mounted electrical connector, only the frame body is attached to the panel, and the terminal section is located at a separate location independent of the panel, and the cable or printed circuit board can be connected to it. After that, the connection work to the connector can be completed by attaching the terminal portion to the frame attached to the panel. Therefore, if the panel-mounted electrical connector of the present invention is used, it is possible to separate the wiring and exterior assembly work, centralize the same work, and assemble it at the final stage when assembling equipment with electrical circuits. This eliminates the occurrence of mistakes, reduces loss in setup time, and streamlines assembly and connection work. In addition, the work of connecting cables or printed circuit boards to the terminals can be done at a separate location unrelated to the panel, making it easier to use connection jigs such as batch connections, further increasing work efficiency. can be measured. Furthermore, by designing the frame so that either the male terminal or the female terminal can be selectively attached to the same frame, it is possible to use the same frame as a male connector. It can easily be used as a female connector.

Next, the present invention will be described in more detail with regard to embodiments of the present invention based on the accompanying drawings.

FIG. 1 is a perspective view, with the panel and connector partially cut away, showing how a panel-mounted electrical connector according to an embodiment of the present invention is used. This panel-mounted electrical connector of the present invention consists of a frame 10 that is mounted and fixed on a panel 40 of equipment, and a terminal section 20 for connecting cables that is attached to the frame 10 after it is mounted and fixed on the panel. It's summery. Reference numeral 30 indicates an example of a mating electrical connector, in this case a female electrical connector, which is coupled to panel mount electrical connectors 10 and 20 from the front side of panel 40. The frame 10 is integrally molded from an insulating material such as plastic, and has a through opening 11 for receiving a terminal portion 20 for cable connection and a portion of a mating connector 30. The frame 10 includes a front portion 10A that seats on the front side of the panel 40, and a rear portion 10B that extends to the back side of the panel 40 through the mounting opening 41 of the panel 40. Fixing screws 1 with tightening nuts 13 are provided on both sides of the front part 10A.
2 is provided. Installation opening 4 of panel 40
Holes 42 through which fixing screws 12 are passed are provided at corresponding positions on both sides of 1. Therefore, the rear part 10B of the frame 10 is passed through the mounting opening 41 of the panel 40, and the fixing screw 12 is passed through the hole 42.
The frame 10 is attached and fixed to the panel 40 by seating the frame 10 on the front surface of the panel 40 and screwing the tightening nuts 13 into each of the fixing screws 12. FIG. 1 shows this state. Elastic tongue pieces 14 are formed on both sides of the rear part 10B of the frame 10 to engage with and lock both sides of the terminal part 20 for cable connection. Furthermore,
A key 15 for preventing incorrect fitting is formed on the side wall of the through opening 11 of the frame 10. As shown in FIG. 1, two keys 15 are provided on one side wall, but only one key (not shown) is provided in the center of the opposite side wall.

In this case, the terminal section 20 for cable connection is assembled with a terminal arrangement block 21 made of an insulating material such as plastic, on which male connection terminals are disposed, and a flat section in between. A protector 25 made of an insulating material such as plastic, which connects the connecting terminals arranged in the terminal arrangement block 21 so as to sandwich the tip of the cable 50 and the core wire of the flat cable 50; It consists of a cable clamp 28 made of an insulating material such as plastic, which in combination with the block 21 and protector 25 clamps the flat cable 50. On both sides of the terminal arrangement block 21, the terminal parts 20 for cable connection are inserted into the through openings 11 of the frame 10.
When the elastic tongue piece 14 is inserted into the frame body 10, the elastic tongue piece 14 is elastically biased outward, and when the insertion is completed, the tip of the elastic tongue piece 14 returns to its pre-biased state due to elastic force. A locking protrusion 22 for locking the terminal portion 20 is formed. Furthermore, a key groove 23 is formed in the side wall of the terminal arrangement block 21 at a position corresponding to the key 15 of the frame 10. At both ends of the cable clamp 28, locking legs 29 are formed which are inserted into combination holes 26 formed at corresponding positions on both sides of the protector 25 and the terminal array block 21 for locking.

In this way, the terminal section 20 for cable connection is
Since it is separated from the frame 10, for example, after connecting the flat cable 50 to the terminal section 20 for cable connection at a location completely different from the panel 40 using an appropriate connection jig, the panel 40 can be connected. By aligning the key 15 and the keyway 23 with the frame 10 attached and fixed to the frame 40, and simply pushing or inserting the cable connection terminal part 20, the cable connection terminal part 20 can be connected to the electrical connector mounted on the panel. Cable connection can be completed. The other end of the flat cable 50 is connected to a predetermined portion of an electrical circuit within the device.

For example, a male electrical connector attached to this panel 40 and connected to a flat cable 50 is a flat cable with a jacket 60.
A female electrical connector 30 connected to the panel 40 is connected from the front side of the panel 40. At this time, the key 31 provided on the connector 30 to prevent incorrect fitting should be aligned with the keyway 23 of the cable connection terminal section 20 of the panel-mounted electrical connector. , proper contact between male and female terminals can be obtained. Lock screws 32 are provided on both sides of the female electrical connector 30. After the electrical connector 30 is connected to the panel-mounted electrical connectors 10 and 20, these locking screws 32 are connected to the fixing screws 1 provided on the frame 10.
Female screw 12B provided at the center of head 12A of 2
These connectors can be locked together by screwing them together. This locked state is shown in FIG.

Here, in addition to its original function, the key 15 for preventing incorrect fitting provided on the frame 10 is used to
0 in the opposite direction, all the pushing force of this electrical connector 30 is received by the frame 10 and the panel 40 to which it is attached, and no force is applied to the terminal part 20 for cable connection. Therefore, it also has the effect of preventing the cable connection terminal portion 20 from falling off from the frame 10.

In the above-described embodiments, the cable connection terminal section 20 is described as being of a male type, but this can easily be replaced with a female type. Further, although the present invention has been described as a connector for a flat cable, the present invention can be easily applied to other types of cables. Furthermore, the terminal section can be made detachable from the frame body after being attached to the panel, so that the terminal section can be easily removed from the frame body even after the terminal section has been inserted into the frame body. .
Furthermore, in the above-mentioned embodiment, the terminal part was configured for cable connection, but this terminal part is
It can also be configured to connect a printed circuit board, thereby making it possible to omit a cable with connectors on both sides for connecting the printed circuit board and the panel.
